and State of Ohio, have invented or discovercd new and usefulImprovements in Water- (Jooled Furnace-l ronts, of which the follow ingis a specification.

My invention relates to water-cooled furnaces; and its principal object.is to construct a durable furnace-door frame attached to thefurnace-binding in such a manner that it can be easily and speedilyreplaced witlwutstopping the operation of the furnace, an object which Iattain in the manner hereinaiterset forth, reference being had to theaccompanyin drawings, in which p a igure 1 is a front view of ,myinvention, 'artlyin section; Fig. 2, a half plan and half liorizontalsection of a portion of 'a furnace includin my invention; 3, .a verticalsection throu h the center of one of the fur nace-doors l ig. 4,31 frontelevation of one o! the water-boxes which I employ; Fig. 5, a Ian ofFig. 4-; Fig. 6; a sideelevation and plan of one of the clamps used inthe central portion ofthe front of the furnaces to hold the Water-boxesin place; Fig. 7, a Frontelevation and plan ofone of the clamps used atthe end ortions of the front of the furi'iaees to clampt e water-boxesin place, and Fig 8 an elevation of oneyof the himling-holts and one ofthe keys for holding the said clamps in place. I v I I Referring to thedrawings, 1 designates the ,U-shaped vertically-arranged channel-ironsresting against the ends of the furnace and those portions of the frontthereof between the furnacedoors. Restiln :wainst these I h nchannel-irons are the I-beams 2, arranged in pairspthe usual bolts 3extending between these pairs of I-beams to clamp the sides of thefurnace together in a manner well known.

Seated between consecutive pairs of L]- shaped irons 1 are thewater-boxes 4, which consist of an upper hollow box-like portion 5,

extending from one iron 1 to the ad acent one and having vertical legs 6extend mg down at each side of the furnace-door o )enin'g 7 to thebottom of said opening. '1 iese waterboxes are provided with inlet-pipesS, which.

extend nearly toihe bottom of the legs 6, and also with outlet-pipes 9,winch are situated near the top of 1; ie water-boxes and vconvey thewater escaping from the boxes into the hopper or funnel 10 at the top ofthe drain pipe 11. The various pipes 8 are connected to the commonfeed-pipe 12, and the several drain-pipes 11 are connected to the commonwastwpipe 15. The front and back walls of the water-boxes are connectedtogether and supported by the cross-pieces 14. i

channcl-irons lare provided with horiz ntal openings 15, which areenlarged at a short distance from their front edges so as to receive theheads of the holts'lfi, whose bodies lie in the openings 15. Theadjacent edges of the consecutive water-boxes in the central portion ofthe furnace front support end porbent outwardly to accoininodatetheouter edges of the I-beams; 2. The bolts ldare provided j hst in frontof the clam-bars 17 with openings or keyways 18, in which are driven thewedges 1%), which force the water boxes tightly against the masonry ofthe fur mace and securely hold. them in place. The outer edges of theend watersboxes are held in place by the shoi t clamping-bars 20, whoseboxes, these clamping-hers being held in place by the wedges 19. Theusualifurnacedoors are fitted to the fronts of these waterboxes in theusual manner, which it is unnecessary to illustrate. It is clear thatthese Witt-(P-liOXOS can be very quickly taken from the furnace-front byremoving the keys and the clamping-bars,"and this without stopping theoperation of the furnace, It will be seen thatthese watcr-lmxes clearthe masonry near the front of the furnace and at the same time providedoor-frames which will not readily burn, out as happens with the usualfur nace l'rontmade of brick.
